AUTOMOBILE-HEATER.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed December 13, 1920. Serial No. 430,396.

T 0 all whom it may concern:

Be it known that 1, LnsLIE C. MILNER, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented new and useful Improvements in Automobile-Heaters, ofwhich the following is aspecification.

The object of this invention is to collect the heat radiating from theexhaust manifold of an automobile and discharge it by the advancemovement of the car and drive of the radiator fan back into the car towarm the passengers.

A further object is to provide means for installation and assembly inmany cars of the present popular design without cutting passagewaysespecially for it, and to provide easy, quick, and simple means'forinstalling the device in cars already in use or made.

I accomplish the above, and otherobjects which will hereinafter appear,by the mechanism illustrated in the accompanying drawing, in which-Figure 1 is a view in side elevation of my invention and the associatedparts of an automobile in which it is shown assembled. Fig. 2 is a topplan view of the invention detached from the car. Fig. 3 is an endelevation looking toward the rear of the car.

respective opposite directions from the dotted line 4-4, 54-5 of Fig. 2.

Like characters of reference indicate like parts in the several views ofthe drawing.

In the drawing, 6' are the engine cylinders, 7 the exhaust manifold, 8the fan which draws atmospheric air in through the radiator (not shown)and discharges it rearwardly longitudinally of the exhaust manifold, 9is the dash, 10 the coil box supported by the dash and 11 is the floorof the body of the car. In some of the most popular cars the dashextends over the adjacent end of the engine and a dished metal segment12 completes the closure between the interior of the ca body and theindent in it for the engine. This segment has a flange with holes forscrews by which it is easily removed, and when removed it provides thenecessary opening into the body of the car from in front where themanifold is located. By cutting away a portion of the segment plate 12in the .vertical plane of the exhaust manifold there is sufiicient roomfor the passage into the car of a hood conveying heat radiated from theexhaust manifold. This hood is in two transversely divided parts 13 and14. The part 13 is open at the bottom for its entire length to receivethe manifold by being pushed down over it. Its lower edges when it is inplace are substantially horizontal, but the roof which is semicircularin cross section slopes from the end next the fan upwardly toward plate12 in order to pass into the car body and to help the airflow. The sidesof 13 are substantially parallel, the one next to the engine beingsomewhat shorterthan the outer one because of the glands from the enginecylinders to the exhaust manifold upon which this side rests. The loweredge of the outer side of the part 13 is turned in to form a stiffeningflange 15 and riveted to theinner wall of this side are the dependingears 16, 16, which are clamped under the adjacent members 17 of theengine. The end of the part 13 is flared outwardly at 18 to form afunnel the better to collect air driven backby the fan 8, and rearwardlysloping finsor b'ailie plates 18 are provided in the upper portions ofthe part 13 to increase the distance of travel of the ai in contact withthe hotmanifold and to more completely i nix the hot and cold air.

The part 14 of the hood is high enough to receive the expanded rear endof 13 and form a dead air pocket over the downwardly bent discharge endof the exhaust manifold. and its tapering walls are closed at the loweras well as lateral and top portions to form a dead-air pocket and todirect the heated current of air to its discharge at its rear throughthe segment plate 12. The member 13 extends rearwardly of and below theexhaust manifold 7 into contact with the downwardly bent discharge endof the latter to increase the size of the dead air pocket.

The end of part 13 is madeoblique at 19 to correspond with andcontactthe sloping bottom of part 14 as clearly shown in Fig. 5.

A receptacle 19, here shown as cylindrical but which may be suitablyformed-in other shapes is fastened by suitable means, here shown asscrews 20, 20, to the segment plate 12, and may be removably secured asshown, to allow of disconnectionin shipping, and the like. The wall ofthe receptacle next to the plate'12 has an opening through which thesmall end of part 14 discharges into the interior of the receptacle. Ajoint is preferably made here by. forming a series ceptacle wall thatwould be otherwise cut away, and bending them out and inside of the part14 where their contact with the walls of the latter makes the joint moresecure. This joint may be made still more secure by soldering on theoutside. The receptacle is long enough to afford. ample distribution ofthe hot air inside the car and for the discharge of the air a horizontalseries of holes is provided which is closed by asliding damper-plate 23,having registering holes that may be brought opposite the holes in thereceptacle wall when it is desired to discharge hot air into the car.

In practice I have found it more convenient to the user to furnish thedevice with segment plate 12 already cut and attached so all he willhave to do is to remove the original plate that comes with the car andreplace it with the new one with my device fitted and attached to it.VThis is done with the -part 13 detached after which the assemarms 17.

bly is completed by slipping part 13 into place and clamping the ears 16under The fins 18 may be omitted in tion what I claim as new and wish tosecure by Letters Patent of the United States, is

1. In an auto-car, the combination with a )assen er bod and an internalcombustion engine having an exhaust manifold, said engine and manifoldbeing located outside of the body, of a heat distributing receptaclelocated within the body, damper means inthe wall of the receptacle, anda hood in two separable parts one of which discharges into the heatdistributing receptacle and extends to the adjacentend of the manifoldand the other part of which extends formost cases 1n climates wheregreat severity of weather wardly fromthe first part and envelops the topand sides of the manifold.

2. In an auto-car, the combination with a passenger body, an internalcombustion engine in a compartment in front of the body separatedtherefrom by a partition, and a hood discharging heat from the enginecompartment into the body, of a plate forming part of said partitionbetween the body and said I engine compartment through which plate thehood passes and to which plate the hood is fastened.

3. In an auto-car, the combination of a body, an internal combustionengine in a compartment in front of the body, a plate closure betweenthe body and engine compartment, a heat distributing receptacle withinthe bodyremovably secured to the plate, and a hood discharging theheated air from the engine compartment into the receptacle. I, 4. In anauto-ca the combination of a body, an internal combustion engine in acompartment in front of the body, a plate closure between the body andengine compartment, a heat distributing receptacle within the bodyremovably secured to the plate, and a hood discharging the heated airfrom the engine compartment into the receptacle, said hood being in aplurality of parts connected by'telescopic joints.

5. In a heater for automobiles, the combination with a body of aninternal combustion engine having an exhaust manifold, a heatdistributing receptacle in said body, and a hood in two parts one ofwhich parts is fas tened to the distributing receptacle and the other ofwhich parts is connected with the first part and also surrounds the topand sides of the exhaust manifold, said hood being separable into itsparts adjacent that end of the exhaust manifold which is nearest thereceptacle.
